BestParts 3.5/2.5 in Hard Disk Tray Type D6 - NAS Drive Caddy

In this review the BestParts 3.5/2.5 in Hard Disk Tray (Type D6) is judged as a straightforward replacement caddy for a long list of Synology-style NAS chassis. The bottom line: it is for users who need a direct, no-frills drive tray that fits models like DS1513+, DS1515, DS1817 and many DX and DS series enclosures. Our review found the tray installs cleanly, includes the necessary screws, and matches the mechanical fit expected from an OEM-style carrier, so it is useful when a lost or damaged caddy must be replaced quickly.

Key Features

• Compatibility: The tray supports a long list of NAS models so replacements are simple when a specific enclosure needs the same form factor.
• Dual drive support: Designed for both 3.5 in and 2.5 in drives, giving flexibility for desktop hard drives or laptop SSDs without extra adapters.
• Included hardware: The package includes one tray and four screws so users can mount a drive straight out of the box without searching for fasteners.
• Form factor match: The carrier follows the expected dimensions and mounting points for the supported NAS models, which preserves tray alignment and drive connection.
• Replacement convenience: As a single-piece caddy, it works well for quick field swaps or to bring a spare on hand for a multi-bay NAS deployment.

Who It's For

This tray is aimed at owners of compatible NAS enclosures who need a direct replacement for a lost, damaged, or broken drive caddy. It suits home lab users, small business admins, and anyone maintaining Synology-style multi-bay boxes listed in the compatibility notes who want a cost-effective like-for-like tray.

It is not for users who need hot-swap electronics, integrated fans, or trays with locking keys and advanced anti-vibration features. If you require branded warranty support tied to an OEM tray or a tray with extra accessories, look for the original manufacturer's parts instead.
